Sono-Tek Corporation, Milton NY, USA plans to exhibit at SemiCon-Intersolar 2011 July 12-14 in San Francisco, CA in booth 2631 (South Hall). Sono-Tek plans to display their ExactaCoat Tabletop Coating System along with working demonstrations of their patented precision ultrasonic spray nozzles.

The ExactaCoat Tabletop Coating System is a fully enclosed programmable XYZ motion system designed for depositing uniform thin-film coatings for electronics and solar applications, including photoresist deposition and various thin-film solar cell coatings.

Particularly suitable for deep well topography coatings, the ExactaCoat is a full coating solution for R&D and low-volume production applications such as depositing photoresist onto wafers and MEMs. The system is also ideal for applying buffer layers onto thin-film solar cells (CdS), active layers such as (CIGS, CdTe), phosphoric doping for inline diffusion, organic solar cell coatings, and fluxing of solder bus lines. The ExactaCoat can be tailored with a number of customizable options including nozzle tilt, dual nozzle, camera, laser pointer, low oxygen atmosphere, and rod coating attachment. Additionally, the ExactaCoat can be configured with any of Sono-Tek’s precision ultrasonic atomizing nozzles to produce highly uniform targeted thin-film coatings with very little overspray and exceptional non-clogging repeatable performance with significant savings in spray materials, maintenance and cleanup costs.

Sono-Tek Corporation has been manufacturing precision ultrasonic coating technology for the electronics industry for three decades and is well-known for being the industry’s leader in ultrasonic spray fluxing. Sono-Tek’s ultrasonic nozzles produce highly uniform targeted thin-film coatings with very little overspray and exceptional non-clogging repeatable performance with significant savings in spray materials, maintenance and cleanup costs.
